  • Patent number: 5004217
    Abstract: A paper feeding device for a paper cassette of an image processing apparatus. The paper cassette is mounted at a specific position or the image processing apparatus in a manner permitting the cassette to be pulled out. A preliminary feed roller feeds the paper on the paper cassette toward a feed roller which is normally energized in a paper pressing direction. When the paper cassette is mounted in the image processing apparatus, the document setting board disposed in the paper cassette is upwardly turned by a pressing mechanism. When the paper cassette is pulled out, the feed roller from the paper cassette is turned in reverse direction. A feed channel to guide the paper from the paper cassette is formed in a curved manner, and a normally turned delivery roller is provided inside the curved channel.

  • Patent number: 4813612
    Abstract: A paper feeding device having a document tray attached to a specified position of an image processing apparatus, a paper cassette mounted onto a specific position in the image processing apparatus in a manner that can be pulled out, and a preliminary feed roller to carry the paper set on the document tray toward a feed roller which is normally energized in paper pressing direction. When a sheet of paper is inserted, the preliminary feed roller is moved in the opposite direction against the energizing force under a balanced condition in transversal direction by a guide member which is turned upward. When the paper cassette is mounted in the image processing apparatus, the document setting board disposed in the paper cassette is upwardly turned by a pressing mechanism. When the paper cassette is pulled out, the feed roller to feed out paper from the paper cassette is turned in reversed direction.
